  Research Notes:

The Chronicon Varadiense names "dux Andreas postea rex, secundus…dux Bella demum rex, tertius dux Levente" as the three sons of "dux Vazul". The Gesta Hungarorum names (in order) "Andrea, Bela et Luenta, filiis Zarladislai" when recording that King István advised them to flee to Bohemia after the mutilation of Vazúl, the commentary suggesting that their father's name was changed by the compiler of the Gesta to disguise the fact that later Hungarian kings were descended from the blinded Vazúl. The Gesta clarifies in a later passage that András was the oldest son. In another passage, the Gesta reports claims that the three brothers were "ex duce Wazul progenitos ex quadam virgine de genere Tatun" rather than legitimate. The Gesta records that the three brothers moved from Bohemia to Poland during the second reign of King Péter, but that "Andreas et Luenta" were embittered by the success of their brother Béla in Poland and moved to Ruthenia, where "duce Lodomeriæ" refused to receive them out of regard for King Péter, and that from there they moved "ad terram…Comanorum". The estimated birth date of his daughter Adelaida suggests that András must have arrived in Kiev before [1039], assuming that she was born from his second marriage. The Hungarian nobles sent envoys to Kiev in Spring 1046 inviting the brothers Levente and András to return, which they did in Autumn 1046.

After the popular uprising which deposed King Peter in 1046, he succeeded as ANDRÁS I "the Catholic" King of Hungary, crowned at Székesfehérvár. The Chronicon Posoniense records that "Petrus rex" was blinded in 1047 and succeeded by "Andreas rex". The Gesta Hungarorum records that King András forced payment of tribute for three years from Austria, Bohemia and Poland, which provoked an attack on Hungary by Emperor Heinrich III. "Andreas…Pannoniorum…Rex" founded Tihan abbey, Balatin by charter dated 1055, signed by "Gilconi comitis, Zache C. Palatii, Wotteh comitis, Ludouici comitis, Ernei comitis, Viti comitis, Martini comitis, Heliæ comitis, Andreæ comitis, Fancel comitis…". When King András crowned his infant son Salamon as associate king in 1057, his brother Béla was provoked into taking action to secure his own rights of succession. The Chronicon Posoniense records that "Andreas rex" crowned "Salamonem filium suum" during his illness. Hungarian forces invaded Byzantine territory in 1059 in reprisal for Byzantium's failure to curb Pecheneg raids in Hungary, but quickly made peace after Emperor Isaakios Komnenos mobilised forces.

In 1060, Béla invaded Hungary with a large force, with Polish support, captured King András who died a few days later, and assumed power. The Gesta Hungarorum records the death of King András in the fifteenth year of his reign and his burial in "Tyhon monasterio". The Chronicon Varadiense records the death in 1060 of "Andreas" and his burial "in suo monasterio Thyan iuxta lacum Balaton". The Chronicon Posoniense records bitter disputes in 1060 between "Andream et fratrem eius Bela" and that "Andreas rex" died, which suggests that the death may have been violent. ¹
